Abstract:
:Tir, a translocated effector protein from enteropathogenic E. coli (EPEC), contains two phosphotyrosines that initiate cellular signaling cascades, leading to localized actin polymerization into pedestals. A recent study now shows that two additional tyrosines within Tir recruit the inositol phosphatase SHIP2 to generate a PI(3,4)P2-enriched membrane platform that stabilizes pedestal assembly.

评论,杂志文章abstract::Neutralizing antibodies (NAbs) are traditionally thought to inhibit virus infection by preventing virion entry into target cells. In addition, antibodies can engage Fc receptors (FcRs) on immune cells to activate antiviral responses. We describe a mechanism by which NAbs inhibit chikungunya virus (CHIKV), the most com...
